Inductive proximity sensors IMP

Category Tag
  • Reduced maintenance costs
  • Extremely resilient and durable
  • Up to 50 times longer service life compared to conventional sensors under pressure cycles
  • Simple compensation of cylinder tolerances
  • Simple integration due to small design
  • Controlled piston deceleration
  • Increased piston service life due to collision prevention at the end of the work cycle


The inductive, high-pressure-resistant IMP sensors are perfectly suited for the query of end positions in hydraulic cylinders. The use of state-of-the-art ASIC and manufacturing technologies from SICK sets new standards in installation size, service life and load capability for the sensors. Due to the stable stainless steel housing and an active high-performance ceramic surface, they are pressure-resistant up to 500 bar. Above-average system throughput is a matter of course for the range of models M5, M8, M12 and M14 thanks to 1 million tested pressure cycles.
